CEM DT-5505 Insulation Tester

The DT-5505 Insulation Tester is an indispensable tool designed to enhance the efficiency and safety of power installations. This advanced tester is equipped to perform comprehensive insulation tests by offering a variety of test voltages, including 125V, 250V, 500V, and 1000V. Under each of these ranges, it can deliver a 1mA test current to effectively manage capacitance loads, ensuring accurate measurements across diverse scenarios.

One of the standout features of the DT-5505 is its ability to automatically discharge capacitive voltages, significantly enhancing user safety by mitigating potential risks associated with stored voltages. Additionally, it includes a live circuit detection system that prevents insulation testing if a voltage greater than 30V is detected. This feature acts as a critical safeguard, protecting both the user and the equipment from hazardous conditions.

The tester is also built with convenience in mind, featuring an auto-range function that allows for measurement of resistance up to 4000 MegaOhm with a resolution of 1Kohm. This broad range ensures that the tester can be used in a variety of electrical settings, from low-resistance installations to high-resistance materials.

For those who need to record and analyze data, the DT-5505 offers Min/Max recording and a Data Hold function, facilitating easy tracking and recording of measurements during extended testing periods. Furthermore, for continuity testing, it provides a robust 200mA short circuit current, allowing for thorough and reliable continuity checks.

These capabilities of the DT-5505 are in line with the strict safety standards set out in the CE document, ensuring that the device not only meets but exceeds the necessary safety regulations required for electrical testing equipment. Whether it’s for installation, routine maintenance, or troubleshooting, the DT-5505 Insulation Tester delivers reliable performance and safety, making it a valuable asset for any electrical professional.
